Study on Fault Diagnosis of Mine Ventilator Based on Genetic Neural Network

In order to improve the accuracy of the fault diagnosis on mine ventilator,an fault detection of mine ventilator based on neural network whose thresholds and connection weights are optimized by genetic algorithm(GA-NN) is proposed in this paper.Using the characteristic of self-learning,self-adaptive and efficient fault tolerant of BP neural networks,the model weaken the human factors to improve the accuracy of the results of the assessment and authority.Simulation results show that the diagnosis method,a higher accuracy and quicker diagnosis,is a more practical fault diagnosis method.
